So serious are the disturbances of the circulation all over the body by these spasmodic suffocation-fits, that rupture of small blood-vessels may occur in the eyes, the brain, in the lungs, and on the surface of the skin. The heart becomes distended, and if originally weakened may be seriously dilated or overstrained; the lungs become congested and inflamed, and any of the numerous accidental germs which may be present will set up a broncho-pneumonia, which is the commonest cause of death in this disease, as in measles. Strangely enough, while, as we do not positively know the germ, and hence cannot state definitely either the cause or the principal seat of the trouble, it is not generally believed that the condition of the lungs or the throat has much to do with the cough. At all events, it is perfectly idle to treat the disease with cough mixtures or expectorants. The view toward which the majority of intelligent observers are inclined is that whooping-cough is an infection, the germ or toxin of which attacks the nervous system, and particularly the great "lung-stomach" (pneumo-gastric) nerve. At all events, the only remedies which appear to have any effect upon the disease are, in the early stages, mild local antiseptics in the nose and throat, and later those which diminish the irritability of the nerves without upsetting the appetite or depressing the general vigor. The disease is, for all its mildness, one of the most obstinate known. A small percentage of cases run a violent course, in spite of the most intelligent and anxious care, both medical and household; but the vast majority of such complications as occur are either caused by carelessness or become serious only if neglected. Treating all children with whooping-cough as emphatically sick children, entitled to every care and excuse from exertion, every exemption and privilege that can be given them until the last whoop has been whooped, would prevent at least two-thirds of the almost ten thousand deaths from whooping-cough that yearly disgrace the United States. To sum up in fine: intelligent, effective isolation of all cases, the mild no less than the severe, would stamp out these Herods of the twentieth century within ten years. In the meantime, six weeks' sick-leave, with all the privileges and care appertaining thereto, will rob them of two-thirds of their terrors. CHAPTER XII APPENDICITIS, OR NATURE'S REMNANT SALE
